The 2015 RECS illuminates the variability and trends in household energy use across the nation’s more than 118 million homes, apartments, and mobile homes. The survey captured over 200 energy-related items from more than 5,600 households and included questions covering new technologies, such as smart thermostats, LED lighting, and tablets. Additional household-level data is scheduled for release in April and the 2015 RECS Consumption and Expeditures estimates will be released starting in early 2018. Additional information is available in an EIA article.
